“VORTEC” 4300 Engine 2.2L Engine
In very cold weather,
0°F (- 18°C) or colder, the engine
coolant heater can help. You’ll get easier starting and
better fuel economy during engine warm-up. Usually,
the coolant heater should be plugged
in a minimum of
four hours prior to starting your vehicle.
To use the coolant heater:
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 110-volt AC outlet.

Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind
of extension cord could.overheat and cause
a fire.
You could be seriously injured. Plug the
cord into
a properly grounded three-prong
110-volt
AC outlet. If the cord won’t reach, use a
heavy-duty three-prong extension cord rated for
at least
15 amps.

(but lower fuel economy) than
SECOND (2). You can
use it on very steep hills, or in deep snow or mud. If the
selector lever
is put in FIRST (1) while the vehicle is
moving forward, the transmission won’t shift into
FIRST (1) until the vehicle is going slowly enough.
1 NOTICE:
If your rear wheels can’t rotate, don’t try to
drive. This might happen if you were stuck in
very deep sand or mud or were up against
a solid
object.
You could damage your transmission.
Also, if you stop when going uphill, don’t hold
your vehicle there with only the accelerator pedal.
This could overheat and damage the transmission.
Use your brakes or shift into
PARK (P) to hold
your vehicle in position on a hill.

To set the parking brake, hold the regular brake pedal
down with your right foot. Push down the parking brake
pedal with your left foot. If the ignition is on, the brake
system warning light will come on.
To release the parking brake hold the regular brake
pedal down.
lr Pull the BRAKE RELEASE
lever. It is located on the
bottom driver’s side of
the
instrument panel.
I NOTICE:
Driving with the parking brake on can cause
your rear brakes to overheat. You may have to
replace them, and you could also damage other
parts
of your vehicle.
If you are towing a trailer and you must park on a hill,
see “Towing a Trailer” in the Index. That section shows
what to do first
to keep the trailer from moving.

3. If you have four-wheel drive with a manual transfer
case shift lever, be sure the transfer case is in
a drive
gear
-- not in NEUTRAL (N).
4. Turn the ignition key to LOCK.
5. Remove the key and take it with you. If you can
remove the key from
your ignition, your vehicle is
in PARK (P).
A CAUTION:
It can be dangerous to leave your vehicle with the
engine running. Your vehicle could move suddenly
if the shift lever is not fully in PARK
(P) with the
parking brake firmly set. If you have four-wheel
drive with
a manual transfer case shift lever and
your transfer case is in NEUTRAL
(N), your
vehicle will be free to roll, even
if your shift lever,
is in PARK (P).
So be sure the transfer case is in a
drive gear -9 not in NEUTRAL (N). And, if you
leave the vehicle with the engine running, it could
overheat and even catch fire. You or others could
be injured. Don’t leave your vehicle with the
engine running unless you have to.

It means that your engine coolant has overheated. If you
have been operating your vehicle under normal driving
conditions, you should pull off the road, stop your
vehicle and turn off
the engine as soon as possible.
In “Problems on the Road,” this manual shows you
what
to do. See “Engine Overheating” in the Index. This
system is called
OBD I1 (On-Board
Diagnostics-Second Generation) and is intended
to assure
that emissions are at acceptable levels for the life of the
vehicle, helping to produce a cleaner environment.
(In
Canada, OBD I1 is replaced by Enhanced Diagnostics.)
The SERVICE ENGINE SOON light comes on to
indicate that there is a problem and service
is required.
Malfunctions often will be indicated by the system before
any problem is apparent, which may prevent more serious
damage to your vehicle. This system
is also designed to
assist your service technician
in correctly diagnosing
any malfunction.

When off-roading takes you downhill, you’ll want to
consider a number
of things:
How steep is the downhill? Will I be able to maintain
vehicle control?
0 What’s the surface like? Smooth? Rough? Slippery?
0 Are there hidden surface obstacles? Ruts? Logs?
Hard-packed dirt? Gravel?
Boulders?
0 What’s at the bottom of the hill? Is there a hidden
creek bank
or even a river bottom with large rocks?
If you decide you can go down a hill safely, then try to
keep your vehicle headed straight down, and use a low
gear. This way, engine drag can help your brakes and
they won’t have to do all the work. Descend slowly,
keeping your vehicle under control at all times.
I
’ CAUF3N:
Heavy braking when going down a hill can cause
your brakes to overheat and fade. This could
cause loss of control and a serious accident.
Apply the brakes lightly when descending a
hill and use a low gear to keep vehicle speed
under control.

you could lose control and have a serious accident.
When driving downhill, avoid turns that take you
across the incline of the hill.
A hill that’s not too
steep to drive down may be too steep to drive across.
You could roll over if you don’t drive straight down.
Never
go downhill with the transmission in
NEUTRAL
(N), or with the clutch pedal depressed
in a manual shift. This is called “free-wheeling.”
Your brakes will have to do all the work and could
overheat and fade.
Am I likely to stall when going downhill?
A: It’s much more likely to happen going uphill.
But
if it happens going downhill, here’s what to do.
Stop your vehicle by applying the regular brakes.

Shift back to a low gear, release the parking brake,
and drive straight down.
If the engine won’t start, get out and get help.

Downloaded from www.Manualslib.com manuals search engine Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have extra
wiring and a heavy-duty turn signal flasher (included
in
the optional trailering package).
The green arrows on your instrument panel will flash
whenever you signal a turn or lane change. Properly
hooked up, the trailer lamps will also flash, telling other
drivers you’re about to turn, change lanes or stop.
When towing a trailer, the green arrows on your
instrument panel will flash for turns even if the bulbs on
the trailer are burned out. Thus, you may think drivers
behind
you are seeing your signal when they are not. It’s
important
to check occasionally to be sure the trailer
bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you don’t shift
down,
you might have to use your brakes so much that
they would get hot and no longer work well, On
a long uphill grade, shift down and reduce your
speed to around
45 mph (70 kdh) to reduce the
possibility of engine
and transmission overheating.
If you have an automatic transmission, you should use
DRIVE (D) when towing a trailer. Operating your
vehicle in DRIVE (D) when towing a trailer will
minimize heat buildup and extend the life of your
transmission. Or, if you have a manual transmission, it’s
better not to use FIFTH
(5), just drive in FOURTH (4)
(or, as you need to, a lower gear).
When towing at high altitude on steep uphill grades,
consider the following: Engine coolant will boil
at a
lower temperature than at normal altitudes. If you turn
your engine off immediately after towing at high altitude
on steep
uphill grades, your vehicle may show signs
similar to engine overheating. To avoid this, let the
engine run while parked (preferably on level ground)
with the automatic transmission in PARK
(P) (or the
manual transmission out of gear and the parking brake
applied) for
a few minutes before turning the engine off.
If you do get the overheat warning, see “Engine
Overheating’’
in the Index.

Downloaded from www.Manualslib.com manuals search engine Engine Overheating
You will find a coolant temperature gage on your
vehicle’s instrument panel.
If Steam Is Coming From Your Engine
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay away
from the engine if you see or hear steam coming
from it. Just turn it
off and get everyone away
from the vehicle until it cools down. Wait until
there is
no sign of steam or coolant before
opening the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch fire. You or
others could be badly burned. Stop your engine if
it overheats, and get out of the vehicle until the
engine is cool.
I NOTICE:
If your engine catches fire because you keep
driving with
no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered by your warranty.
